IMPROVEMENTIN MACHINES FOR HARVESTING BEANS.

Specification forming part of Letters Patent No. 24,4182, dated June 21, 1859.

lowing is a full, clear, and exact 'description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a longitudinal vertical section of myinvention,takenin theliuexx, Fig. 3. Fig. 2 is a transverse vertical section of the same, taken in theliney y, Fig. 3.' Fig. 3 is an inverted plan ofthe same.

lSimilar letters of .reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of rotary sickles peculiarly arranged for cutting the bean-stalks, and using in connection with said sickles guide-platesl and endless conveying-chain, platform, and discharging plate or rake, the whole being placed in a mounted frame and arranged substantially as hereinafter described, whereby the beans may be cut and discharged in gavels on the ground.

To enable those skilled in the art to fully unstand and construct my invention, I will proceed to describe it.

A represents a frame, which may be formed of two parallel bars, a, connected by traversebars b b, and having thills B B attached to one end. This frameAis mounted on two wheels, U (l,0ne of which, C,is attached to the axle D, and the other,C, allowed to rotate freely on it. To the inner side of the wheel G a toothed rim,E,is attached concentrically. This rim is toothed on its inner periphery and gears into a pinion, F, which is placed at one end of a shaft, G, said shaft being htted transversely in the frame A,and has a toothed wheel,H,on it at about its center. The wheel H may be termed a double-beveled wheel, and it gears into two bevel-pinions, I I, one at each side ot it. These pinions I I are placed on the upper ends of inclined shafts JJ, the upper parts of which have their bearings in a transverse bar, 0in the frame A, the lower bearings being in bars dd, the ends of which are curved upward and attached to the'franie A. The shafts J J have au inclined position, one shaft having a reverse position to the other, (see Fig. 2,) and to the lower end ofeach shaft Jacircular sickle, K, is attached. The sickles K are placed ou their respective shafts at right angles, and consequently have inclined positions, as yshown clearly in Fig. 2. The sickles K K are formed ofcircular steel plates provided with scallopedshaped teeth, the teeth of'one sickle working between those of the other, as shown clearly in Fig. 3. i

L is a shaft, which has its bearings in supports M on the frame-A. The shaft L is directly over and in the same plane with shaft G, and receives its motion from shaft G by means ofa belt, e. (See Figs. 1 and 2.) On the shaft L two pulleysff are placed, and similar pulleys, g, are tted on shafts N N, which are placed on the bars d d-one near their front and the other near their back ends, as shown clearly in Fig. l. Around the pulleysj'g of the three shafts L N N an endless chain of rods, O, works. chains, h h, with transverse rods attached at suitable distances apart. The lower portion of the chains of rods 0 is about parallel with the bars del and is quite near the sickles K K.

PPare guides-plates, the front ends of which are ofcurved form, and are suspended by chains j from a traverse-bar, b, of the frame. The'back parts of the guide-plates are pivoted to the bars d d. The guide-plates P P are somewhat inclined, corresponding to the inclination of the sickles K Kand the space between the lsickles is iu line with the space or bite7 ofthe sickles.

Q is a platform, the back part of which is suspended by rods It' k from the back of the frame A, the front end of the platform being suspended by rods l l from the bars d d.

To the back traverse-har' b of the frame A a rake-handle, m, is attached by a swivelconnection, n, the rake 0 being of any proper form, (a simple plate would answer,) the rake or plate resting on the platform. (See Fig. lI.) The back end of the frame A has a semicircular rod, p, attached, which serves as a handle for the u operator.

The operation is as follows: As the machine is drawn along the sickles K K are rotated in the direction indicated by the arrows through Y the medium of the gearing Fl F H I I, and the bean-stalkswill be cut thereby near the surface of the ground, the machine being so guided This device is formed of two that the row of beans will be i-n line with the bite ofthe sickles. The plates P l? gather up the stalks that may be lodged or bent over, so that theywill enter into the bite ofthe sickles and be prevented from coming in contact with and winding around the shafts J Land the endless chain of rods O, which move in the direction indicated by arrow 1, Fig. 1, convey the stalks on the platform Q, from which they may be rakedrby the operator actuating the handle m. The operator or attendant grasps the rod or handle p, and is enabled to elevate the sickles above any ordinary obstructions hy simply depressing the back part of the inachine. The siekles KK arerotated With considerable rapidity in order to operate effectually, as the stalks of beans are quite tough and can not be cut by ordinary cuttin g devices. The rotary siekles are therefore an important fea ture of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The employment or use ofthe rotary siekles K K, provided with scalloped-shaped teeth.,

andarranged to operate substantially as andl S. VAN RENSSELAER NEWMAN.
